National Ai Day is celebrated on April 26 and focuses on the meaning of the word "Ai," which translates to "adoration," "affection," or "love" in Chinese and Japanese. In Japan, "Ai" is predominantly used as a female name, while it can be given to boys in Chinese culture. The pronunciation is similar to the English word "eye," though the written forms differ between the two languages. Notable individuals with this name include Chinese activist Ai Wei Wei, Japanese tennis player Ai Sugiyama, and singer-songwriter Ai Otsuka. The day serves as an opportunity to appreciate the cultural significance of the name and its representation in various media, including video games and cartoons.
